Judging from reviews the AMS rad is rather restrictive the Radical rad is low/medium restriction.
The heatkiller IV basic Acetal is one of the least restrictive blocks out there.

So would one D5 pump handle this loop with good flow atleast 1gpm? Or should i get my self another D5 pump and combine them with EK top for 2 D5's in serial for more head pressure?

I went with the Aquacomputer rads because they are clean inside no flux that may end up in my blocks as a side note i think two 480 rads should be good for a cpu and gpu loop while getting good temps as well as silence. And Norprene tubing for no plasticizer issues or leeching just want a clean system.

Some reviews compared the AMS rad with the radical rad and the AMS won the radical 2 was much thiner then the AMS the Radical have in my list is the radical 4 which is even thicker then a monsta rad.

Anyway your feedback regarding one or 2 D5 pump(s) is much appreciated

You should be fine with one pump, but then again custom loops are just as much about looks and bling as they are about practicality, and you can get some really good looking dual pump tops.

Aren't you going overboard with quick disconnects though? 3 pairs is a lot.

Thanks for the reply,

The reason why regarding 2 pumps is the Aquacomputer AMS rad which is rather restrictive plus im using another 480 rad and two water blocks as well as 3 pair of QD4's i really hope one is good enough and maintain 1gpm.

The 3 pair of QD4's are there for easy maintaining my loop one qd4 between pump and cpu one qd4 between gpu and rad and another qd4 on the rad. So i can easily dismantle the loop for cleaning once a year or 1.5 year. The last qd4 is on the rad that is attached outside my case left side.

I was wondering what lead you to the idea that a 1LPM flow rate, on this water loop would be a sufficient flow rate, that would allow for a good use of the components. the reason I ask is that I have done testing on this and have found that flow rate has a direct result on how well the radiators are able to perform. if you have the time please have a look at this test build I did that shows what kind of effect flow rate had on my loop. keep in mind that this loop has as few restrictions as possible.http://www.overclock.net/t/1573189/serial-vs-parallel-9-6lpm

it makes no actual sense to use quick disconnects between every component. you are adding restriction to everyday use because you think it will be easier to maintain your loop which youre planning to be once a year.
choosing aquacomputer rads because you dont want to clean them. you will need to clean them regardless.

I like what you have planned for the upgrade, good sensible components as well.
The build quality of the Aquacomputer rads is great, they even have threaded inserts for the fan screws.
And certainly the qd's will lead to less hassle for disconnecting components, etc.

I've been running dual D5's with an EK Serial top for years now.
The redundancy gives me peace of mind, and it's worked really well.
One D5 is likely enough, but two is certainly nice to have.

Mine is an older dual D5 top, but imo the new EK XTop Revo Dual D5 top is a well-designed product.

I actually agree with pc-illiterate on this one, which surprises me more than it surprises you trust me, and don't take his opinion personally that's just his delivery, but he knows his stuff.

I guess what seems strange is you said you have been water cooling for 7 years but the questions in your op are basic questions that any experienced water cooler should already know. Even the most restrictive rad will be the least restrictive component in the loop and most people don't choose rads based on restriction. You absolutely have the right to chose whatever rad you want, but the reasoning you chose it is usually considered very superficial.

Also, you are looking for high flow and least restriction but are choosing the most most restrictive fittings available, QDC's. They are usually used by people who change components every few months. If your maintaining your loop once a year it's a completely unnecessary component to use.

And concerning the dual pumps, again an experience water cooler knows when to use dual pumps. It takes a lot more than you have to consider dual pumps a necessity, most people use them as redundancy.

Don't take any feedback insultingly, take with a grain of salt and consider it more knowledge in your repratoir.

Thanks for the reply,

I ditched the dual rad setup im just going with one single Aquacomputer AMS 840 rad this should give me good temps at low 700rpm fans. The D5 should handle that loop including 2 pairs of QD4.
And yeah been thinking about dual D5 my self as a safety measure for in case on pump dies, but then again you have auto shut down if the cpu gets to hot. Yup redundancy ie dual D5 sure is great just need to think about it. D5 should be a reliable pump just like the Aquastream XT pump is use in both of my WC systems one of them been running for 7 years now still going strong (knocking on wood). Better have a new pump then use a 7 year old pump....Siilent and pretty powerfull otherwise i would likely bought a Aquastream ultra pump the new one they released. But i already have a new and unused D5 with ek top it would be a waste not to use it.
